whats the best way to use monocote as trim schemes without having air bubbles forming underneath.need help

I've done it three ways. Try all three and stick with the one your best at. One is with trim solvent. This is pretty easy on small designs but takes an extra set of hands for long stripes. You just wet the base down with solvent
roll the top color into place and push out the bubbles with a cotton ball. Make sure you dont touch the back of the covering with the solvent. It will make a clear spot in the top piece. Two is with a iron and hot sock. For a stripe just tack down one end. Hold the other end up with one hand and work the iron in a circular motion back and forth pushing the covering down a 1/8" at a time. Start at the end you tacked down working your way towards the end your holding up. If your doing a star start in the middle and work out. The trick to this is the temp of your iron. It takes just the right amount of heat. To much and you get bubbles, not enough and it will peel in flight. Also if you are covering a large area. Put some holes in the base coat in the area to be overlaid. This can be done with a woodpecker or a piece of balsa with a bunch of T-pins in it. Please keep in mind if your top color is light like yellow or white and the base color is dark the holes you poke will show in the sun. Third way looks the best but is very time consuming. You just cut the stripes and lay them down cold with soapy water.Push out the excess with a paper towel then apply heat when it's dry. It takes so long because you cant handle the plane until the stripes are dry and that takes several hours.Like anything else practice makes perfect.
Take your time and practice on your old plane if you have one. later daveo
